Having discussed the foundation / drainage plans with my neighbour over the holiday period he seemed happy enough with the extension left hand foundation but more concerned about a left hand drain (due to proximity). There’s no Party Wall Act (i.e. section 6(1) / 6(2) Adjacent Excavation...

2 metres at 1/40th to close that 50mm gap gives me a fair bit of hope. I've shifted about 150 tons around (shovel/wheelbarrow) in the back garden so think I already know it pretty well ... groundstation for setting out and Optical Level with tripod/staff, with care, I think i'll be accurate...

The fall calculation and positioning of the various elements was actually undertaken exactly so as a clash never occurs (i.e. the whole thing "fits"). There are some close shaves though with foul obvert below to storm invert above down to 50mm (or less) in places. I've no idea if BC would...

That all sounds eminently sensible and deserving of a deep dive - I had expected nothing less from you when I decided to post on the topic. All that and the resident particle physicist's had a bit of a laugh too. What's not to like :giggle: Thanks again.

Do you imagine an overriding improvement (e.g. dismissing extension/garage alleyway foul complications & garage floor storm I.C. complications) by redesign and trying to send everything down the left, or something more subtle perhaps?

Ah, above interior floor level? I'd like to go straight down through the floor to avoid clutter, if possible. Edit: ther's a stub stack in the design for the internal bathroom but not the ensuite

The distance between the existing left wall of my bungalow and neighbour's is approx 2.4m Any drains that might go down that alley would be closer to my wall found than 1 metre. With very shallow foundations it's probably not a great area for drain runs and involve lots of concrete fill. The...

To Building Control e.g. connecting to main sewer for ground floor toilet

As per attached? The BIGT 160mm stackable risers I have seen are 250mm tall so 3 or 4 needed to take the it's outlet invert to 930mm. I don't think i've ever read of a limit to the depth of one of these ... should that be ok? Thanks.

If you mean drop internally vertically down onto the top of the drain then .... since neither would be upstream roddable directly from an IC nor, explicitly, roddable downstream (into a branch connected directly to an IC), my understanding is that the decision could be contentious. For example...

If i'd known anything about drainage at the time i'd probably never have made the purchase :unsure: Everything is new. I'll add a pdf that has work in progress of the entire drainage scheme in it - making things a bit clearer (hopefully). The bottom left is the head of the foul drain run...

I'm currently using Inkscape to draw a Building Contol Application for flat roof extension to / renovation of my suspended wooden floor bungalow - please see a screenshot of the drainage (with calculation) as a work in progress attached. The image currently displays 450mm foul Inspection...
